NetPA Series Setup uide (Continued) Step 3 Connecting the NetPA to the Network Using standard C cable, connect the RJ45 connector E of the NetPA to a LAN for digital audio transport (see Creating a Physical Dante Network on page 9). Step 4 Audio Output Connector Stereo audio output connector Wire the speakers to the output connector of the H using the 4pole captive screw connector, as shown below. Do not tin the wires! Mono audio output connector Wire the speakers to the output connector of the NetPA 0070V I using the 2pole captive screw connector, as shown below. Do not tin the wires! 70 V OUTPUTS Step 5 Setting the High Pass Filter (HPF) On the NetPA 0070V, use a Tweeker or small screwdriver to toggle the high pass filter switch J between Off (no filtering) and 80 Hz (default). Setting the switch to 80 Hz prevents the saturation of speaker input transformers by low frequency signals. The high pass filter can be safely turned off only if the filtering is applied upstream of the amplifier. Step 6 Remote Connector The 3.5 mm, 2pin captive screw remote control port D forces the unit into standby mode when the remote standby pin is shorted to ground. The amplifier wakes from standby and resets the inactivity timer when the connection is reopened. See the user guide for details. Step 7 Line Out Connector Connect an amplifier or other device to the 3pole, 3.5 mm captive screw connectors C for channel and channel 2 () or the single channel (NetPA 0070V). Wire as shown below. Tip Ring Sleeve Balanced Output Audio Output Wiring Tip NO round Here Sleeve Unbalanced Output " (5 mm) MAX. Do not tin the wires! TENTION: For unbalanced audio outputs, connect the sleeves to the ground contact. DO NOT connect the sleeves to the negative ( ) contacts. TENTION : Pour l audio asymétrique, connectez les manchons au contact au sol. Ne PAS connecter les manchons aux contacts négatifs ( ). NOTE: The signal that comes out of the line output is the same signal that goes into the amplifier stage, prior to the gain potentiometers. (The same audio content coming out of channel amplified output comes out of the channel line output.) 2
Product Category Step 8 Powering On the Equipment TENTION: The amplifier must be powered on last. TENTION : L amplificateur doit être allumé en dernier. Reconnect all power cables and switch on all other equipment before powering on the amplifier. The front panel power LED of the NetPA lights green. Step 9 Installing Dante Controller for Windows Software Dante Controller from Audinate is required to select and route digital inputs and outputs to connected Dante compatible devices. Install Dante Controller on a PC running Microsoft Windows 7 or newer. For full details about computer requirements, see the product page on the Extron website. Dante Controller must be installed to rename the connected NetPA to assist identification on the network.

Save the file to your desktop (or other known location). 7. Locate and doubleclick the saved Dante Controller file to begin installation. 8. Follow the onscreen instructions. When the installation completes, close the installation dialog. Step 0 Dante Network Setup Rename the NetPA Dante Controller autodiscovers all Dante devices on the network and advertises itself to allow other Danteenabled devices to communicate with it. The default device name is the word NetPA followed by the last six digits of the MAC address of the device. Multiple devices on the same network can present difficulty identifying inputs and outputs. To avoid confusion, each device must be renamed to a unique identifier. NOTE: To simplify renaming, connect only one Dante device to the network at a time. As each device is renamed, it can remain connected. Ensure the control computer and the NetPA are connected to the same network.. From the start menu select All Programs > Audinate > Dante Controller > Dante Controller. The Dante Controller Network View screen opens. All Dante devices on the network are discovered and listed. 4
Product Category 2. From the toolbar, select Device>Device View. 3. The Dante Controller Device View dialog opens. Select your device from the (Select a Dante Device...) dropdown list. NOTES: If there are multiple NetPA s connected to the network that have not been renamed, to identify an individual device you must obtain the MAC address of the desired device from the label on the rear panel. The identify device tool can also be used to identify the unit (see Identifying the Physical Device on page 6). The Device View dialog populates with the selected NetPA information. 4. Click the Device Config tab to open the device configuration page. 5. In the Rename Device panel, enter the new name of the device in the text field. No spaces are allowed in the name. 5
NetPA Series Setup uide (Continued) 6. Click Apply. A warning opens. 7. Click Yes to enter the new name, then close the Device Configuration dialog. The new name is written to the NetPA. Repeat as necessary for all NetPA devices. NOTE: After the NetPA is renamed, it can remain connected to the network. However, subsequent devices must be connected one at a time and renamed before the next device is connected. Identifying the Physical Device If the amplifier needs to be physically identified, the identify device tool can be used to aid in its location.. Start with steps through 3 of Rename the NetPA on page 4. 2. To identify the NetPA, click on the eye icon on the toolbar. 3. Both the front panel power LED (see figure 6, A, on page 0) and the rear panel link LED F (see figure, F, on page ) blink amber at a rate of 0.5 Hz for ten seconds, after which the LEDs return to their previous state. 4. Locate the unit with the blinking LEDs. NOTE: For advanced network setup, refer to the user guide. 6
Product Category Step Dante Operation Select Devices After the receiver inputs of the NetPA are configured, they must be routed to the other Dante devices on the audio network. Dante Controller is required.. Ensure the control computer and NetPA are connected to the same network. 2. From the start menu select All Programs > Audinate > Dante Controller > Dante Controller. The Dante Controller Network View screen opens. Dante Controller autodiscovers Dante devices on the network and advertises itself to allow other Danteenabled devices to communicate with it. Device inputs are Dante receivers (listed vertically on the left) and device outputs are Dante transmitters (listed horizontally across the top). Transmitters (outputs) connect to receivers (inputs) using the connection matrix. 3. Click the + box next to the NetPA (NetPAClassroom0) in the Dante Receivers column to show all device inputs. 4. Click the + box next to the transmitter (DMP28LectureHall) in the Dante Transmitter row to show all device outputs. 7
NetPA Series Setup uide (Continued) Route Inputs and Outputs. Click the + box next to the input channels (receivers) on the NetPA (NetPAClassroom0 in the example above). All device outputs (transmitters) display horizontally. 2. Click the junction of the desired connection (Example: DMP28LectureHall Output0 to NetPAClassroom0 INPUTMONO). A checkmark at the junction indicates the connection is made. A checkmark is also placed next to the receiver channel. NOTE: An input (receiver) can connect to only one output (transmitter). An output (transmitter) can connect to multiple inputs (receivers). 3. Click the junction again to disconnect the input from the output. See the Dante Controller section of the NetPA Series user guide for information on Dante Controller operation. Step 2 Setting the ain Potentiometer Turn up the gain potentiometer to the desired level. When the pot is set to 0 db, and a 0 dbfs signal is transmitted through the Dante port, the amplifier outputs full power. Use a Tweeker or small screwdriver to adjust the audio input gain for the corresponding channel. The analog potentiometers control the gain from = (full attenuation) to 0 db (no gain) to + 6 db gain. NOTE: The potentiometer affects the gain post DAC and pre amplifier stage. The gain potentiometer does not adjust the level of the line output. 6 4 6 4 8 0 8 0 0 NetPA 0070V 6 4 8 0 0 8

The and NetPA 0070V have an RJ 45 connector located on the back panel that accepts a standard network cable. A DMP 28 based Dante network can be configured in a star or daisy chain network topology using the four port switch and the Dante Controller in switched mode. Star network topology places one DMP 28 C as the central unit, which connects directly to up to three more units. Alternatively, a larger network switch in place of the central DMP 28, allows more than four NetPA s to connect in the star configuration. MIC/LINE INPUTS OUTPUTS DIITAL I/O DMP 28 C Star Network Topology Figure 4. Star Network Topology A daisy chain configuration can also be used. Each NetPA device can connect only to the end of the chain. MIC/LINE INPUTS OUTPUTS DIITAL I/O DMP 28 AXP 50 C # AXP 50 C #2 INPUTS Daisy Chain Network Topology INPUTS Figure 5. Daisy Chain Topology Hybrid versions combining the star and daisy chain topologies can be built, but a ring topology, or any topology that creates a duplicate connection causes a connection failure in Dante Controller. NOTE: Connections between ports in either a star or daisy chain network do not need to be sequential ( to 2, 2 to 3, 3 to 4), nor do they need to be made between the same port numbers ( to, 2 to 2, 3 to 3, 4 to 4). NOTE: At the moment, Dante is not compatible with EEE (Energy Efficient Ethernet) technology. Care should be taken when using a network switch with this technology in a Dante network. If using a managed switch, ensure that it supports disabling EEE on all ports that will be used for Dante traffic. If using an unmanaged switch, do not use models that support the EEE function, as it can not be disabled on these models. For more information on this topic, see the Audinate website. Resetting the NetPA The NetPA utilizes DHCP addressing by default. A recessed reset button on the rear panel (see figure,, on page ) initiates a reset mode. Reset sets the IP addressing mode to DHCP (Dante default), clear the previous IP address, and reset the device name to default. NOTE: Initiating a reset while the NetPA is connected to a transmitting device severs that connection. To reset the NetPA, press and hold down the reset button for ten seconds until both of the rear panel RJ45 Ethernet port LEDs blink twice. NOTE: When the NetPA is first powered on, or reset, the default name shall be NetPAxxxxxx where xxxxxx are the last six digits or letters of the MAC address of the unit. Ethernet Port LEDs 9
